Data Store Function for my Inventory?

[NOVITUS12]

Hi everyone I’m currently working on an Inventory System.My only Problem is that it doesn’t save the tool when I die, leave or respawn I got some photos here:
First I buy a Gamepass

Then it appears in my Inventory

Then I respawn

And as you see it’s gone

I got two script here and pls tell me the Data Store Code and where I have to put it:

InventoryScript:
"’
local inventoryEvent = game.ReplicatedStorage.Remotes.InventoryEvent

game.Players.PlayerAdded:Connect(function(player)

local inventory = player:WaitForChild("Inventory")

local inventoryFrame = player.PlayerGui:WaitForChild("InventoryGui").InventoryFrame.ItemsFrame:GetChildren()

inventory.ChildAdded:Connect(function(Item)
	inventoryEvent:FireClient(player, Item.Name, true)
end)

end)

inventoryEvent.OnServerEvent:Connect(function(player, ItemName, Value, button)

 if Value == false then
		local SelectedItem = player.Inventory:FindFirstChild(ItemName)
		local backpack = player.Backpack:GetChildren()
		local stuff = player.Character:GetChildren()
		
		if #backpack == 0 and not player.Character:FindFirstChildWhichIsA("Tool") then
			button.Text = "Unequip"
			button.BackgroundColor3 = Color3.new(255,0,0)
			SelectedItem:Clone().Parent = player.Backpack
		else
			for i,v in ipairs(backpack) do
				button.Text = "Equip"
				button.BackgroundColor3 = Color3.new(0,255,0)
				v:Destroy()
			end
			for i, v in ipairs(stuff) do
				if v:IsA("Tool") then
					button.Text = "Equip"
					button.BackgroundColor3 = Color3.new(0,255,0)
					v:Destroy()
				end
			end
		end
 end

end)

InventoryLocalScript:

"’
local InventoryEvent = game.ReplicatedStorage.Remotes.InventoryEvent
local itemFrame = script.Parent:FindFirstChild(“ItemsFrame”)

InventoryEvent.OnClientEvent:Connect(function(ItemName, Value)
if Value == true then

	local ItemButton = script.Parent.ItemsFrame.ItemButton:Clone()
	ItemButton.Visible = true
	ItemButton.Name = ItemName
	ItemButton.Text = ItemName
	ItemButton.Parent = itemFrame
	
	local equipButton = script.Parent.EquipFrame["EquipButton"]
	
		ItemButton.MouseButton1Click:Connect(function()
			script.Parent.EquipFrame.Title.Text = ItemName
			script.Parent.EquipFrame.Title.Visible = true
			equipButton.Visible = true
		end)
end

end)
